Many philosophers worry that the classical computational theory of mind (CTM) engenders epiphenomenalism. Building on Block’s (1990) discussion, I formulate a particularly troubling version of this worry. I then present a novel solution to CTM’s epiphenomenalist conundrum. I develop my solution within an interventionist theory of causal relevance. My solution departs substantially from orthodox versions of CTM. In particular, I reject the widespread picture of digital computation as formal syntactic manipulation.1.

It has been argued that nonreductive physicalism leads to epiphenominalism about mental properties: the view that mental events cannot cause behavioral effects by virtue of their mental properties. Recently, attempts have been made to develop accounts of causal relevance for irreducible properties to show that mental properties need not be epiphenomenal. In this paper, I primarily discuss the account of Frank Jackson and Philip Pettit. I show how it can be developed to meet several obvious objections and to (...) capture our intuitive conception of degrees of causal relevance. However, I argue that the account requires large-scale miraculous coincidence for there to be causally relevant mental properties. I also argue that the same problem arises for two apparently very different accounts of causal relevance. I suggest that this result does not show that these accounts, on appropriate readings, are false. Therefore, I tentatively conclude that we have reason to believe that irreducible mental properties are causally irrelevant. Moreover, given that there is at leastprima facie evidence that mental properties can be causally relevant, my conclusion casts doubt on nonreductive physicalist theories of mental properties.

In this paper I present an analysis of causal relevance for properties. I believe that most of us are already familiar with the notion of a causally relevant property. But some of us may not recognize it "under that description." So I begin below with some intuitive explanations and some illustrative examples.

Causal selection and priority are at the heart of discussions of the causal parity thesis, which says that all causes of a given effect are on a par, and that any justified priority assigned to a given cause results from causal explanatory interests. In theories of causation that provide necessary and sufficient conditions for the truth of causal claims, status as cause is an either/or issue: either a given cause satisfies the conditions or it does not. (...) Consequently, assessments of causal parity and priority require more resources, which can either be additional or part of the causal analysis itself. While adding resources in terms of a theory of causal explanation has been standard, here we develop a unified conceptual analysis that includes a range of different precise causal concepts that allows for assessments of causal priority in terms of different kinds of causal relevance.

It is natural to think that our ordinary practices in giving explanations for our actions, for what we do, commit us to claiming that content properties are causally relevant to physical events such as the movements of our limbs and bodies, and events which these in turn cause. If you want to know why my body ambulates across the street, or why my arm went up before I set out, we suppose I have given you an answer when I say (...) that I wanted to greet a friend on the other side of the street, and thought that my arm's going up would be interpreted by him as a signal to stop for a moment. This widely held view might be disputed, but I shall not argue for it in this paper. I want to start with the view that our beliefs and desires and other propositional attitudes are causally relevant, in virtue of their modes and particular contents, to our movements, in order to investigate the consequences for analyses of thought content. For this purpose, I argue, in sec. II, for three necessary conditions on causal relevance: (a) a nomic sufficiency condition, (b) a logical independence condition, and (c) a screening-off condition. In sec. III, I apply these conditions to relational and functional theories of thought content, arguing that these theories cannot accommodate the causal relevance of content properties to our behaviour. I argue further that, on two plausible assumptions, one about the dependence of the mental on the physical, and the other about the availability in principle of causal explanations of our movements in terms of our non-relational physical properties, content properties can be causally relevant only if they are nomically type-correlated, relative to certain circumstances, with non-relational physical properties of our bodies. In sec. IV, I respond to a number of objections that might be advanced against this conclusion. (shrink)

Failures are sometimes, but not always, causally relevant to events. For instance, the failure of the sprinkler was causally relevant to the house fire. However, the failure of the dam upstream to break (thus inundating the house with water) was not. Similarly, failures to prevent harms are sometimes, but not always, morally wrong. For instance, failing to save a nearby drowning child is morally wrong. Yet, you are also in some sense “allowing” someone on another continent to drown right now, (...) and this seems permissible. Here, I argue that these two issues are connected. Roughly, I argue that it is prima facie morally wrong to fail to prevent a particular harm if and only if one’s omission is causally relevant to that harm’s occurrence. The result is that, contrary to what Peter Singer claims, failing to donate to famine relief is not morally equivalent to failing to rescue a drowning child in a shallow pond. (shrink)

To determine whether dispositions are causally relevant, we have to get clear about what causal relevance is. Several characteristics of causal relevance have been suggested, including Explanatory Power, Counterfactual Dependence, Lawfullness, Exclusion, Independence, and Minimal Sufficiency. Different accounts will yield different answers about the causal relevance of dispositions. However, accounts of causal relevance that are the most plausible, for independent reasons, render the verdict that dispositions are causally relevant.

This paper centers around the notion that internal, mental representations are grounded in structural similarity, i.e., that they are so-called S-representations. We show how S-representations may be causally relevant and argue that they are distinct from mere detectors. First, using the neomechanist theory of explanation and the interventionist account of causal relevance, we provide a precise interpretation of the claim that in S-representations, structural similarity serves as a “fuel of success”, i.e., a relation that is exploitable for the (...) representation using system. Then, we discuss crucial differences between S-representations and indicators or detectors, showing that—contrary to claims made in the literature—there is an important theoretical distinction to be drawn between the two.

In this paper, I focus on a problem related to teleological theories of content namely, which notion of function makes content causally relevant? It has been claimed that some functional accounts of content make it causally irrelevant, or epiphenomenal; in which case, such notions of function could no longer act as the pillar of naturalized semantics. By looking closer at biological questions about behavior, I argue that past discussion has been oriented towards an ill-posed question. What I defend is a (...) Very Boring Hypothesis: depending on the representational phenomenon and the explanatory question, different aspects might be important, and it is difficult to say a priori which ones these might be. There are multiple facets to biological functionality and causality relevant for explaining representational phenomena, and ignoring them will lead to unmotivated simplifications. In addition, accounting for different facets of functionality helps dispense with intuition-based specifications of cognitive phenomena. (shrink)

In everyday causal explanations of human behaviour, known generally as folk psychology,' the causal powers of the mental seem to be taken for granted. Mental properties such as perceptions, beliefs, and desires, are all called upon in causal explanations of events that are deemed intentional. Jaegwon Kim's exclusion principle has led him to deny mental properties causal efficacy unless they are metaphysically reduced to physical properties, but what of their causal relevance? By giving up (...) the assumption of causally efficacious mental properties, has Kim put into question the explanatory value of explanations with mental descriptions? In other words, if a lower order neurological causal explanation involving a causally efficacious property is at hand, does it make the higher order mental explanation irrelevant and therefore redundant? If we are to save the explanatory importance of higher order predicates, and thus the causal explanations of the special sciences and folk psychology, we need an account of how such properties can be relevant as opposed to irrelevant in causal explanations, even though they may not be causally efficacious. Frank Jackson's and Philip Pettit's notion of program explanation tries to do just this. (shrink)

My aim in this thesis is to explain how a non-reductionist metaphysics can accommodate the causal relevance of the psychological and of the special sciences generally. According to physicalism, all behavior is caused by brain-states; given "folk-psychology", behavior is caused by some psychological state. If psychological states are distinct from brain states, then our behavior is overdetermined and this, it is claimed, is unacceptable. I argue that this consequence is not unacceptable. I claim that our explanatory practice should (...) guide our ontological commitment. If we can offer true explanations that appeal to more than one event, then we are committed to overdetermination for the event explained. I argue that accepting overdetermination is not absurd and that we can give an adequate account of causal relevance for psychological and other supervenient properties. The result is a partial defense of both property and event pluralism. Recent work by Davidson, Fodor, Jackson, Kim, Pettit and Yablo receives explicit and critical discussion. (shrink)

The problem facing us in this paper is that of how to analyze the notion of causal relevance. This is the inverse relation of causal dependence: A is causally irrelevant to C iff C is causally independent of A. As an example of causal relevance, consider: Example 1: A - The American astronaut on Mir scratched his left ear exactly an hour ago B - I am writing this paper right now. Intuitively, A was not (...) causally relevant to B. It is this kind of intuition that I’ll mostly be relying on when analyzing the notion of causal relevance. (shrink)

I argue that (strong) psychophysical supervenience, properly understood as a metaphysical dependence or determination relation, helps to account for the causal/explanatory relevance of mental properties because (1) it blocks a standard epiphenomenalist objection to the effect that an event's mental properties are 'screened off' by their physical properties: (2) it accounts for the _causal (and not merely _normative or merely _nomological) status of commonsense psychological generalizations; (3) it accounts for the _nonredundancy and _irreducibility of psychological explanations.

Many mathematicians are platonists: they believe that the axioms of mathematics are true because they express the structure of a nonspatiotemporal, mind independent, realm. But platonism is plagued by a philosophical worry: it is unclear how we could have knowledge of an abstract, realm, unclear how nonspatiotemporal objects could causally affect our spatiotemporal cognitive faculties. Here I aim to make room in our metaphysical picture of the world for the causal relevance of abstracta.

Nonreductivist physicalists are increasingly regarded as unwitting epiphenomenalists, since their refusal to reduce mental traits to physical properties allegedly implies that even if there are mental causes, none of them produces its effects by virtue of its being a type of mental state. I examine and reject a reply to this concern that relies on the idea of ​​"tropes". I take the failure of the tropes-based model of causal relevance to illustrate a confusion at the heart of the (...) notion of causal relevance, a notion that is central to the critique of non-reductive physicalism. I aim to dispel the idea that non-reductive physicalism is committed to epiphenomenalism. (shrink)

causal relevance, a three-place relation between event types, and circumstances, and argue for a logical independence condition on properties standing in the causal relevance relation relative to circumstances. In section 3, I apply these results to show that functionally defined states are not causally relevant to the output or state transitions in terms of which they are defined. In section 4, I extend this result to what that output in turn causes and to intervening mechanisms. In (...) section 5, I examine the implications of this result for functional theories of mental states. In section 6, I distinguish between functional descriptions of properties and functional definitions of properties, and argue the former present no obstacle to mental states being causally relevant to behavior, but that this is so because they do not treat mental states as functional states. In section 7, I examine the nature of explanations that appeal to functional states or properties. section 8 identifies some difficulties that arise in thinking about specifically conscious mental states as functional states. section 9 is a brief conclusion.

The problem this paper deals with is the problem of how dispositional properties can have causal relevance. In particular, the paper is focused on the question of how dispositions can have causal relevance given that the categorial bases that realise them seem to be sufficient to bring about the effects that dispositions explain. I show first that this problem of exclusion has no general solution. Then, I discuss some particular cases in which dispositions are causally relevant, (...) despite of this exclusion problem. My claim is that dispositions have causal relevance in selection or recruitment processes, when they are converted into teleological functions. (shrink)

Frank Jackson and Philip Pettit have defended a non-reductive account of causal relevance known as the ‘program explanation account’. Allegedly, irreducible mental properties can be causally relevant in virtue of figuring in non-redundant program explanations which convey information not conveyed by explanations in terms of the physical properties that actually do the ‘causal work’. I argue that none of the possible ways to spell out the intuitively plausible idea of a program explanation serves its purpose, viz., defends (...) non-reductive physicalism against Jaegwon Kim’s Causal Exclusion Argument according to which non-reductive physicalism is committed to epiphenomenalism because irreducible mental properties are ‘screened off’ from causal relevance by their physical realizers. Jackson and Pettit’s most promising explication of a program explanation appeals to the idea of invariance of effect under variation of realization , but I show that invariance of effect under variation of realization is neither necessary nor sufficient for causal relevance.

Davidson argues that mental properties are causally relevant properties. I argue that Davidson cannot appeal to ceteris paribus causal laws to ensure that these properties are causally relevant, if he wishes to retain his argument for anomalous monism. Second, I argue that the appeal to supervenience cannot, by itself, give us an account of the causal relevancy of mental properties. I argue that, while mental properties may indeed 'make a difference' to the causally efficacious properties of events, this (...) is not sufficient to show that mental properties are causally relevant.

How do mental states come to be about something other than their own operations, and thus to serve as ground for effective action? This papers argues that causation in the mental domain should be understood to function on principles of intelligibility (that is, on principles which make it perfectly intelligible for intentions to have a causal role in initiating behavior) rather than on principles of mechanism (that is, on principles which explain how causation works in the physical domain). The (...) paper considers Dharmakīrti’s kāryānumāna argument (that is, the argument that an inference is sound only when one infers from the effect to the cause and not vice versa), and proposes a naturalized account of reasons. On this account, careful scrutiny of the effect can provide a basis for ascertaining the unique causal totality that is its source, but only for reasoning that is context‐specific. (shrink)

I argue against counterfactual theories of causation , develop a pragmatic version of the Covering Law view, and offer a causal theory of counterfactuals. ;The initial idea of CTCs is that event a causes event b if b would not have occurred, if a had not occurred. David Lewis proposes this view as a solution to problems of "effects" and "epiphenomena". I argue that CTCs cannot solve these problems. Covering Law theories can, but only by rejecting traditional Humean accounts (...) of laws. ;Following Nancy Cartwright , I argue that there is no a priori route from probabilistic association to causal relevance, and that distinguishing causal relevance from mere association requires further causal knowledge. Some recent literature on causal modelling is also examined. ;Much causal knowledge concerns rough, approximate ceteris paribus laws and generalizations. I examine these and argue that they involve important pragmatic components. ;Many aspects of intuitive causal judgment and reasoning are explained by ceteris paribus causes. For example, many causes are preventable, and only ceteris paribus causes could be prevented. Ceteris paribus causes are capacities, which make similar contributions to different circumstances, and interact with each other . The pragmatic features of ceteris paribus laws hold equally of ceteris paribus causes. ;Singular and generic causes are unified by appeal to the a posteriori impossibility of "action at a distance". The locality of causal relations requires that causes act by continuous intervening processes. Singular causes and effects are instances of generic causal process types. ;Numerous cases of unclear and conflicting intuitions about causes and effects are explained by contextual factors . ;I explain away the attraction of CTCs by offering a causal account of counterfactuals. It is natural to express causal facts using counterfactuals because the truth conditions of counterfactuals are direct consequences of causal facts. (shrink)

This article examines three aspects of the problem of understanding Benjamin Libet’s idea of conscious will causally interacting with certain neural activities involved in generating overt bodily movements. The first is to grasp the notion of cause involved, and we suggest a definition. The second is to form an idea of by what neural structure(s) and mechanism(s) a conscious will may control the motor activation. We discuss the possibility that the acts of control have to do with levels of supplementary (...) motor area activity and with the activation of populations of excitatory and inhibitory interneurons. The third aspect is to conceive of the main features of Libet’s proposed conscious mental field (CMF). We consider both an ontological and an epistemological interpretation of the CMF being nonphysical. In an attempt to refute the idea that Libet’s dualist mind–brain interactionism would violate the law of conservation of energy, we suggest that a CMF may alter the probability of the ion-channel gating by influencing structures of a size to which quantum mechanics needs to be applied. We argue that given the suggested definition of cause, and given the epistemological interpretation of the CMF being nonphysical, nothing would necessarily rule out that an element of a CMF, conscious will, may causally interact with neural activities in the brain. This defense of the idea of conscious will being causally efficacious has a bearing not only on the understanding of the mind–brain relation but also on the free will debate. (shrink)

I advance a new theory of causal relevance, according to which causal claims convey information about conditional probability functions. This theory is motivated by the problem of disjunctive factors, which haunts existing probabilistic theories of causation. After some introductory remarks, I present in Section 3 a sketch of Eells's (1991) probabilistic theory of causation, which provides the framework for much of the discussion. Section 4 explains how the problem of disjunctive factors arises within this framework. After rejecting (...) three proposed solutions, I offer in Section 6 a new approach to causation that avoids the problem. Decision-theoretic considerations also support the new approach. Section 8 develops the consequences of the new theory for causal explanation. The resulting theory of causal explanation incorporates the new insights while respecting important work on scientific explanation by Salmon (1971), Railton (1981), and Humphreys (1989). My conclusions are enumerated in Section 9. (shrink)

Ever since Davidson first articulated and defended anomalous monism, nonreductive physicalists have struggled with the problem of mental causation. Considerations about the causal closure of the physical domain and related principles about exclusion make it very difficult to maintain the distinctness of mental and physical properties while securing a causal role for the former. Recently, philosophers have turned their attention to the underlying metaphysics and ontology of the mental causation debate to gain traction on this issue. Cynthia MacDonald (...) and Graham MacDonald have followed suit and argue that the solution to the nonreductivist’s troubles lies in a particular metaphysical view of events. They claim that an appropriately formulated property exemplification account of events resolves the problem and secures the causal relevance of mental properties. I argue that while this approach might get us the causal efficacy of mental events, it does not provide the sought-after causal relevance of mental properties. I show that the reason MacDonald and MacDonald stumble on the problem of causal relevance is—ironically—due to features of their view of events. (shrink)

Robb & Heil describe a higher-order version of the popular Causal Exclusion Problem. In particular, they ask whether the argument that led to a change in focus from event causation to causal relevance of properties can be iterated, leading us to focus on the causal relevance of properties of those properties, or properties of properties of those properties, and so on. In this paper, I investigate this curious higher-order problem and argue that the appeal of (...) both the original argument and its iterations reflects a lack of understanding of causal relata and a problem with the notion of causal relevance.

Can heritability estimates provide causal information? This paper argues for an affirmative answer: since a non-nil heritability estimate satisfies certain characteristic properties of causation (i.e., association, manipulability, and counterfactual dependence), it increases the probability that the relation between genotypic variance and phenotypic variance is (at least partly) causal. Contrary to earlier proposals in the literature, the argument does not assume the correctness of any particular conception of the nature of causation, rather focusing on properties that are characteristic of (...) causal relationships. The argument is defended against Lewontin's (1974) locality objection and Kaplan and Turkheimer's (2021) recent critique of Genome-Wide Association Studies (GWAS). (shrink)
